Electrodermal Testing near me in Royal Oak, Michigan. Electrodermal Testing such as CEDSA represents a breakthrough in providing modern complementary health-care and problem identification to the general public at a reasonable cost. It utilizes a computer-based, integrated instrument that measures the energy balances and imbalances of the body. CEDSA maps the energetic levels of your body’s organs, endocrine glands, and digestive, immune, and lymphatic systems and indicates any vitamin or mineral imbalances. In addition to CEDSA, you may be surprised to know that EKG, EEG, EMG, and MRI use the same energetic field of the body to make their findings for medical diagnosis.
